DESCRIPTION OF EMBODIMENTS

User equipment (UE) connected to a wireless network may report information to the network regarding the quality of communications received. For example, the UE may report back information that indicates the strength of a signal transmit from a base station. The information reported may be used by the base station to determine how to send information to the UE or to determine if a UE should be handed over to another base station. In long term evolution (LTE) systems, a UE may communicate with the network using one or more channels, carriers, or beams. In order to determine operating parameters for one or more UEs, the network may therefore benefit from additional channel state information. In order to efficiently transmit the channel state information to the network, the UE may transmit a reporting message over an extra-large physical uplink shared channel (xPUSCH).

UEs connected to the network using multiple input and multiple output (MIMO) connections may report information regarding various channels used by the UE. In a MIMO system, the UE and the base station may each use multiple antennas to transmit and receive signals. The signals may then be received through several different channels. For example, in some embodiments a UE and a base station may each use 2 antennas for transmitting and receiving signals. In such a system, there are 4 channels through which the data may be transmit (e.g., from the first antenna of the transmitter to the first antenna of the receiver, from the first antenna of the transmitter to the second antenna of the receiver, from the second antenna of the transmitter to the first antenna of the receiver, or from the second antenna of the transmitter to the second antenna of the receiver). The UE may measure the quality of signals received through each of these channels.

In some embodiments, a base station may utilize multiple antennas to for beams to produce stronger signals to UEs connected to the network. For example, MIMO antenna systems forming beams may be applied in a 5G system to enhance the coverage and improve the spectrum efficiency. For example, a base station of the network in a MIMO system, such as an evolved nodeB (eNodeB), may maintain a number of Transmitting (Tx) and Receiving (Rx) beams. In order to coordinate the beams to provide various UEs with appropriate signals, the UE may need to report Channel State Information (CSI) as well as beam information to the network. For example, the UE may report a channel quality indicator (CQI) that indicates the quality of transmissions received by the UE. The eNodeB may use this feedback information to determine a modulation scheme to use when sending transmissions to the UE. The beam information provided as feedback from the UE may contain the Tx beam index (BI) and the Beam Reference Signal Rcceiving Power (BRS-RP). In some embodiments, a UE may report more than one BRS-RPs in order to support flexible beamforming and dual beam operation. For example, reporting multiple beams may indicate which beam to use to communicate with the UE, how to use multiple beams to communicate with the UE, or who to direct a beam to target the UE.

In some embodiments, the UE may provide feedback comprising one or more of CSI, channel quality indicator (CQI), a precoding matrix indicator (PMI), corresponding rank index (RI), and beam index (BI). The channel quality indicator may indicate the modulation and coding schemes used by the UE. The CQI may be based on a PMI and RI for the UE. In some embodiments, the CQI may be an integer value that indicates the quality of the channel. In response to receiving the CQI, the network may send transmissions at a higher coding rate and with different modulation schemes. The PMI indicates which precoding matrix should be used by the network for communications. The PMI may be based on the RI, and may be selected from a codebook based on the RI. The codebook may be a stored set of PMT that is used by the UE and the network to determine coding and modulation schemes for transmissions. For example, a codebook may store precoding information in a lookup table that is used by the UE and an eNodeB when sending transmissions. The RI may indicate a number of layers that the UE is using during decoding of downlink transmission. The BI may indicate a particular number of layers for the beam on which the UE is reporting.

The UE may report 5G Uplink Control Information (xUCI) including CSI and BRS-RP reports using an associated 5G physical uplink shared channel (xPUSCH) in response to an uplink grant received from the eNodeB. For example, in some embodiments, the eNodeB may provide an uplink grant to the UE that indicates which information to provide to the network. For example, the eNodeB may instruct the UE to report the beam information by explicitly triggering the BRS-RP report in an uplink grant. For example, a scheduling trigger in an uplink grant may include a control element that acts as a BRS-RP report indicator. In some embodiments, the eNodeB may include a BRS-RP report indicator in the uplink grant that indicates whether the UE is to report beam information. For example, a BRS-RP report indicator with a first value may indicate the BRS-RP report using xPUSCH is enabled and a BRS-RP report indicator with a second value may indicate that BRS-RP reporting is not enabled. If BRS-RP is not enabled, the UE may report feedback information including CSI without BRS-RP reporting.

In some embodiments, the UE may report the BRS-RP as a MAC control element (CE). The BRS-RP information may be transmit to the network using use a particular logic channel ID (LCID) to indicate the MAC CE for BRS-RP reporting. An example for the MAC CE for BRS-RP reporting is depicted in FIG. 2. The MAC CE may include an indication of the BRS-RP, the sub-frame index in which the BRS-RP is measured, and the beam on which the BRS-RP is measured. In some embodiments, the UE may report multiple BRS-RPs. For example, the BRS-RPs may be measured for more than one beam or more than one sub-frame for a particular beam. In some embodiments, the multiple BRS-RPs are may be reported to the network as individual MAC CEs in a single MAC protocol data unit (MAC PDU).

In some embodiments, the BRS-RP may be reported in a message associated with CSI for the UE. For example, the BRS-RP or other beam information may be transmitted to the network along with CSI information. In some embodiments, the UE may transmit one or more BRS-RPs to the network with CSI in a particular sub-frame based on predefined system information. For example, the UE may be configured by the uplink grant or higher layer signaling to report one or more BRS-RPs to the network. In some embodiments, the channel coding scheme for the BRS-RPs and the CQI may be the same.

In some embodiments, the UE may report CSI using xPUSCH sub-frame n upon decoding an uplink grant in that sub-frame that includes an indication to report CQI in the xUCI scheduled for uplink transmission to the network. The CSI report may be associated with one CSI-RS processes for the UE. In some embodiments, the network may not request more than one CSI report for a given sub-frame. In some embodiments, the UE may be semi-statically configured by higher layers to feedback CQI and precoding matrix indicator (PMI) and corresponding rank index (RI) and beam index (BI) on the same xPUSCH by the setting of reporting modes by the network. For example, the network may set the UE to report CQI and PMI based on the modes defined in Table 1 below.

TABLE 1 PMI Feedback Type No Single Multiple PMI PMI PMI PUSCH CQI Wideband CQI Mode 1-0 Mode 1-1 Feedback UE Selected type (sub-band CQI) Higher Layer- Mode 3-0 Mode 3-1 Mode 3-2 Configured (sub-band CQI)

During reporting operations, the UE may select one or more beams and report one or more associated BIs. The number of beams reported may be determined based on the associated CSI process. The modes described in Table 1 may determine the feedback provided by the UE. As shown in the table, the UE may operate to report in three types of xPUSCH CQI feedback: wideband CQI. UE selected sub-band CQI, or higher layer configured sub-band CQI. The UE may also provide three types of PMI feedback: no PMI, single PMI, or multiple PMI.

In wideband CQI the UE may operate in mode 1-0 or mode 1-1. In mode 1-0 a UE reports a wideband CQI value which is calculated assuming transmission on set S sub-bands. Furthermore, the reported CQI values are calculated conditioned on the reported RI. In mode 1-1, a single precoding matrix is selected from the codebook assuming transmission on set S sub-bands. A UE shall report a wideband CQI value which is calculated assuming the use of the single precoding matrix in all sub-bands. The UE shall report the selected single precoding matrix indicator.

In higher layer configured sub-band CQI, the UE may operate in one of modes 3-0, 3-1, or 3-2. In mode 3-0, the UE may report a wideband CQI value that is calculated assuming transmission on a set S of sub-bands. The UE may also report one sub-band CQI value for each sub-band in set S. The sub-band CQI value may be calculated assuming transmission only in the sub-band. The report CQI values may be calculated conditioned on the reported RI.

In mode 3-1 the UE may select a single precoding matric from the codebook assuming transmission only in a set S of sub-bands. The UE may also report one sub-band CQI value for each sub-band in the set S, which are calculated assuming the use of the single precoding matrix in all sub-bands and assuming transmission in the corresponding sub-band. The UE may also report a wideband CQI value which is calculated assuming the use of the single precoding matrix in all sub-hands and transmission on the set S of sub-bands. The UE may report the selected single precoding matrix indicator with the report.

In mode 3-2 the UE may select a preferred precoding matrix from the codebook assuming transmission only in the selected sub-band. The UE may report may include one wideband CQI value per codeword. The wideband CQI value may be calculated based on CQI of a set of sub-bands. For example, assuming the use of the corresponding selected precoding matrix in each sub-band and transmission on the set of sub-bands, the UE may calculate the wideband CQI value based on sub-band CQI values. The UE may report the selected single precoding matrix indicator for each sub-band in the set of sub-bands. In some embodiments, the UE report may also include one sub-band CQI value for each sub-band of the set of sub-bands reflecting transmission over the single sub-band and using the selected precoding matrix in the corresponding sub-band. The reported PMI and CQI values may be calculated based on the reported RI.

In reporting CQI values for wideband and respective sub-bands, the UE may encode the sub-band CQI using a 2 bit sub-band differential CQI offset level. The offset level may be set as the sub-band CQI index minus the wideband CQI index. An example mapping from the differential CQI value to the offset level may be given by table 2 below. In some embodiments, the mapping may be set differently.

The sub-band size supported for various wideband bandwidths may be given according to the table below. Accordingly, the UE or network may determine which mode of reporting to use for the UE based on the sub-band size supported. The system bandwidth listed in the table may is listed according to the number of downlink resource blocks available. In some embodiments other sizes of sub-bands may be supported or other bandwidths may be available to the system.

Embodiments of modulation/demodulation and encoder/decoder functionality are not limited to these examples and may include other suitable functionality in other embodiments.

In some embodiments, the baseband circuitry may generate reports of CSI to transmit to the network as instructed. For example, the baseband circuitry may generate a report including BRS-RP, CSI, CQI, RI, BI, or other information regarding the quality of communications for a channel or beam associated with the UE. Such a report may be encoded by the baseband circuitry and provided through RF circuitry for transmission to the network over xPUSCH. In some embodiments, the baseband circuitry may also process signals received from the network to determine how to report channel or beam information to the network. For example, the baseband circuitry may process signals instructing the UE which information to include in a report based on a mode provided by the network.

In some embodiments, the baseband circuitry 104 may include elements of a protocol stack such as, for example, elements of an evolved universal terrestrial radio access network (EUTRAN) protocol including, for example, physical (PHY), media access control (MAC), radio link control (RLC), packet data convergence protocol (PDCP), and/or radio resource control (RRC) elements. A central processing unit (CPU) 104 e of the baseband circuitry 104 may be configured to run elements of the protocol stack for signaling of the PHY, MAC, RLC, PDCP and/or RRC layers. For example, in some embodiments, the baseband circuitry may encode a MAC CE with BRS-RP information and CSI information for reporting to an associated eNodeB. In some embodiments, the baseband circuitry may include one or more audio digital signal processor(s) (DSP) 104 f. The audio DSP(s) 104 f may be include elements for compression/decompression and echo cancellation and may include other suitable processing elements in other embodiments. Components of the baseband circuitry may be suitably combined in a single chip, a single chipset, or disposed on a same circuit board in some embodiments. In some embodiments, some or all of the constituent components of the baseband circuitry 104 and the application circuitry 102 may be implemented together such as, for example, on a system on a chip (SOC).

In some embodiments, the baseband circuitry 104 may provide for communication compatible with one or more radio technologies. For example, in some embodiments, the baseband circuitry 104 may support communication with an evolved universal terrestrial radio access network (EUTRAN) and/or other wireless metropolitan area networks (WMAN), a wireless local area network (WLAN), a wireless personal area network (WPAN). Embodiments in which the baseband circuitry 104 is configured to support radio communications of more than one wireless protocol may be referred to as multi-mode baseband circuitry.

RF circuitry 106 may enable communication with wireless networks using modulated electromagnetic radiation through a non-solid medium. In various embodiments, the RF circuitry 106 may include switches, filters, amplifiers, etc. to facilitate the communication with the wireless network. RF circuitry 106 may include a receive signal path which may include circuitry to down-convert RF signals received from the FEM circuitry 108 and provide baseband signals to the baseband circuitry 104. RF circuitry 106 may also include a transmit signal path which may include circuitry to up-convert baseband signals provided by the baseband circuitry 104 and provide RF output signals to the FEM circuitry 108 for transmission.

In some embodiments, the RF circuitry 106 may include a receive signal path and a transmit signal path. The receive signal path of the RF circuitry 106 may include mixer circuitry 106 a, amplifier circuitry 106 b and filter circuitry 106 c. The transmit signal path of the RF circuitry 106 may include filter circuitry 106 c and mixer circuitry 106 a. RF circuitry 106 may also include synthesizer circuitry 106 d for synthesizing a frequency for use by the mixer circuitry 106 a of the receive signal path and the transmit signal path. In some embodiments, the mixer circuitry 106 a of the receive signal path may be configured to down-convert RF signals received from the FEM circuitry 108 based on the synthesized frequency provided by synthesizer circuitry 106 d. The amplifier circuitry 106 b may be configured to amplify the down-converted signals and the filter circuitry 106 c may be a low-pass filter (LPF) or band-pass filter (BPF) configured to remove unwanted signals from the down-converted signals to generate output baseband signals. Output baseband signals may be provided to the baseband circuitry 104 for further processing. In some embodiments, the output baseband signals may be zero-frequency baseband signals, although this is not a requirement. In some embodiments, mixer circuitry 106 a of the receive signal path may comprise passive mixers, although the scope of the embodiments is not limited in this respect.

In some embodiments, the mixer circuitry 106 a of the transmit signal path may be configured to up-convert input baseband signals based on the synthesized frequency provided by the synthesizer circuitry 106 d to generate RF output signals for the FEM circuitry 108. The baseband signals may be provided by the baseband circuitry 104 and may be filtered by filter circuitry 106 c. The filter circuitry 106 c may include a low-pass filter (LPF), although the scope of the embodiments is not limited in this respect.

In some dual-mode embodiments, a separate radio IC circuitry may be provided for processing signals for each spectrum, although the scope of the embodiments is not limited in this respect.

In some embodiments, the synthesizer circuitry 106 d may be a fractional-N synthesizer or a fractional N/N+1 synthesizer, although the scope of the embodiments is not limited in this respect as other types of frequency synthesizers may be suitable. For example, synthesizer circuitry 106 d may be a delta-sigma synthesizer, a frequency multiplier, or a synthesizer comprising a phase-locked loop with a frequency divider.

The synthesizer circuitry 106 d may be configured to synthesize an output frequency for use by the mixer circuitry 106 a of the RF circuitry 106 based on a frequency input and a divider control input. In some embodiments, the synthesizer circuitry 106 d may be a fractional N/N+1 synthesizer.

In some embodiments, frequency input may be provided by a voltage controlled oscillator (VCO), although that is not a requirement. Divider control input may be provided by either the baseband circuitry 104 or the applications processor 102 depending on the desired output frequency. In some embodiments, a divider control input (e.g., N) may be determined from a look-up table based on a channel indicated by the applications processor 102.

Synthesizer circuitry 106 d of the RF circuitry 106 may include a divider, a delay-locked loop (DLL), a multiplexer and a phase accumulator. In some embodiments, the divider may be a dual modulus divider (DMD) and the phase accumulator may be a digital phase accumulator (DPA). In some embodiments, the DMD may be configured to divide the input signal by either N or N+1 (e.g., based on a carry out) to provide a fractional division ratio. In some example embodiments, the DLL may include a set of cascaded, tunable, delay elements, a phase detector, a charge pump and a D-type flip-flop. In these embodiments, the delay elements may be configured to break a VCO period up into Nd equal packets of phase, where Nd is the number of delay elements in the delay line. In this way, the DLL provides negative feedback to help ensure that the total delay through the delay line is one VCO cycle.

In some embodiments, synthesizer circuitry 106 d may be configured to generate a carrier frequency as the output frequency, while in other embodiments, the output frequency may be a multiple of the carrier frequency (e.g., twice the carrier frequency, four times the carrier frequency) and used in conjunction with quadrature generator and divider circuitry to generate multiple signals at the carrier frequency with multiple different phases with respect to each other. In some embodiments, the output frequency may be a LO frequency (fLO). In some embodiments, the RF circuitry 106 may include an IQ/polar converter.

In some embodiments, the FEM circuitry 108 may include a TX/RX switch to switch between transmit mode and receive mode operation. The FEM circuitry may include a receive signal path and a transmit signal path. The receive signal path of the FEM circuitry may include a low-noise amplifier (LNA) to amplify received RF signals and provide the amplified received RF signals as an output (e.g., to the RF circuitry 106). The transmit signal path of the FEM circuitry 108 may include a power amplifier (PA) to amplify input RF signals (e.g., provided by RF circuitry 106), and one or more filters to generate RF signals for subsequent transmission (e.g., by one or more of the one or more antennas 110).

In some embodiments, the UE device 100 may include additional elements such as, for example, memory/storage, display, camera, sensor, and/or input/output (I/O) interface.

FIG. 2 illustrates an example network environment 200 according to an embodiment. The network environment 200 may include a UE 100 as described above with reference to FIG. 1. The UE 100 may communicate with a network through an eNodeB 205. As shown in FIG. 2, the eNodeB 205 may communicate with one or more beams 210A-210C. The beams may be formed by the eNodeB 205 in order to improve transmission power to UEs connected to the network. The eNodeB 205 may form the beams using multiple antennas in a MIMO system. In order to produce a beam in a particular direction, the eNodeB 205 may delay transmission to one antenna of a pair of antennas. The delay may cause the signals produced by the pair of antenna to constructively interfere in one direction, and destructively interfere in other directions. In some embodiments, there may be multiple pairs of antennas to produce beams in different directions. The different beams may then be used to spatially multiplex signals transmit by the base station to different UEs. For instance, some UEs may connect to the network through beam 210A, while others may connect through beam 210B or 210C.

In order to provide feedback on the strength of signals received by UE 100 that is communicating with eNodeB 205, the UE may transmit one or more indications of the quality of signals received. For example, the UE may provide an indication of the strength of the signal received from one or more beams provided by the network. Accordingly, the UE 100 may measure the strength of signals received from the eNodeB 205, as well as measuring other indications of quality such as signal to noise ratio.

Based on the CSI received from the UE 100, the eNodeB 205 may modify the modulation and coding schemes used to communicate with the UE 100. For example, if the UE 100 reports high quality channel information, the eNodeB 205 may transmit downlink information to the UE 100 with more efficient encoding and modulation. On the other hand, if the UE reports low quality channel information, the eNodeB 205 may transmit downlink information with slower encoding and modulation, but in a manner that improves the error rate for the communications.

FIG. 3 illustrates, for one embodiment, example components of an eNodeB 205. For example, the eNodeB illustrated in FIG. 3 may be the same or similar to the eNodeB 205 depicted in FIG. 2. In some embodiments, the eNodeB 205 may include application circuitry 202, baseband circuitry 204, Radio Frequency (RF) circuitry 206, front-end module (FEM) circuitry 208 and one or more antennas 210, coupled together at least as shown. The components of eNodeB 205 may perform operations similar to those of corresponding component of UE 100 discussed above. For example, baseband circuitry 204 of eNodeB 205 may perform operations similar to those of baseband circuitry 104 of UE 100.

The components of eNodeB 205 may also perform additional or different operations compared to those of UE 100 to enable the eNodeB 205 to request and process beam information and CSI reports received from the UE. For example, the antennas 210 of the eNodeB 205 may generate one or more beams for downlink transmissions to one or more UEs as discussed above with reference to FIG. 2. The baseband circuitry 204 of the eNodeB may modulate a random access response to provide an uplink grant to a UE. The uplink grant may indicate to the UE beam information and CSI to report to the eNodeB 205. The baseband circuitry 204 may also process beam information and CSI reported from one or more UEs. For example, the baseband circuitry 204 may decode xPUSCH received at the eNodeB 205 from one or more UEs. Furthermore, based on the received CSI and beam information, the baseband circuitry 204 may update the coding and modulation schemes at the base station based on the CSI and beam information. For example, if a UE reports an increasing strength of the BRS-RP, the eNodeB 205 may use a coding or modulation scheme that provides increased downlink transmission speeds. The coding and modulation schemes may be set by the baseband circuitry 204 based on coding and modulation schemes stored in the memory associated with the baseband circuitry.

FIG. 4 is a flow chart 400 illustrating processes performed by a UE to report beam information to a network. Beginning in block 410, the UE receives an uplink grant message from an eNodeB. In some embodiments, the uplink grant may be received at the UE in a random access response over the physical downlink control channel (PDCCH). The UE may demodulate the response in order to process the uplink grant received in the PDCCH data. The uplink grant may be provided by the network so that the network can receive feedback information regarding the quality of communications received by the UE. The uplink grant may include scheduling information for the UE for providing feedback information. In some embodiments, the uplink grant may provide a scheduling trigger for sending one time beam information. For example, the uplink grant may include a control element that indicates to the UE to report feedback information for one or more CSI or beam information. In some embodiments, the uplink grant may provide for periodic reporting of beam information by the UE. For example, a control element in the uplink grant may indicate to the UE to report CSI or beam information at a scheduled time or frequency to the network.

In block 420, the UE determines that the uplink grant from the base station comprises a BRS-RP report indicator. The UE may determine how the uplink grant instructs the UE to transmit beam information. For example, the UE may determine what mode of reporting the UE should use as discussed above with reference to Table 1. The UE may also determine when and how to report BRS-RP information. For example, the UE may report the BRS-RP information on a xPUSCH in response to a scheduling trigger to send the information over the channel at a designated time. In some embodiments, the UE may instead send the BRS-RP information as a MAC CE as part of a MAC PDU. In some embodiments, the UE may report BRS-RP information to the network with associated CSI during CSI reporting. For example, the UE may determine that it is to report the BRS-RP on the same channel coding scheme as is used for CSI reporting.

In block 430, in response to determining that the uplink grant includes a BRS-RP indicator, the UE may generate a BRS-RP report. In order to generate the BRS-RP report, the UE may measure the signal strength of one or more beams received at the UE according to the instructions received from the network. In some embodiments, the UE may also use the signal strength in order to generate an index value for reporting to the network. For example, the UE may generate a beam index that indicates to the network which modulation and coding scheme to use for communications with the UE.

In block 440, the UE transmits the BRS-RP report to the base station. For example, the report may be transmit on xPUSCH as indicated by the uplink grant as a particular report, as a MAC CE, or associated with CSI. The baseband circuitry may cause the UE to transmit the BR-RP report by encoding the report in a message and sending the report through RF circuitry and front end circuitry to one or more antennas of the UE.

FIG. 5 illustrates a MAC CE that may be used by a UE to report beam information to an eNodeB. As discussed above, this is one embodiment of a way for a UE to report information to the eNodeB. The MAC CE illustrated in FIG. 5 is an example implementation. In various embodiments, the structure of a MAC CE for reporting beam information may be implemented differently, but with similar characteristics to the MAC CE illustrated in FIG. 5.

The MAC CE illustrated in FIG. 5 comprises 3 octets of data. The first information provided by the UE in the MAC CE may be a BRS index. The BRS index may provide the beam information to the eNodeB. The beam information may include an indication of which beam is measured by the UE. The next information provided in the MAC CE is the BRS-RP. The BRS-RP indicates the strength of the signal received by the UE for the measured beam. The SF value of the MAC CE may indicate the sub-frame index in which the BRS-RP is measured. The B value of the MAC CE may indicate the receiving beam flag. The receiving beam flag may indicate a flag that is provided be the received beam. The reserved bits are not used by the UE to convey information in the MAC CE. In some embodiments, a UE may send multiple MAC CEs as illustrated in FIG. 5 as part of a single MAC PDU. For example, the UE may measure the signal strength of more than one beam for transmission to the network. The baseband circuitry may generate a single MAC PDU with a MAC CE for each of the measured beams. The MAC CEs may then be transmit as a single MAC PDU be the UE.

FIG. 6 is a flow chart 600 illustrating processes performed by an eNodeB to request beam information from a UE. Beginning in block 610, the eNodeB generates an uplink grant message comprising a scheduling trigger for a UE. The uplink grant request may include information indicating to the UE one or more beams or channels to measure and send feedback information to the eNodeB.

In block 620, the eNodeB transmits the uplink grant message to the LYE. For example, the uplink grant message may be sent as a radio resource control (RRC) message or a MAC signal to the UE. The uplink grant message may include scheduling information for the UE. Upon receiving the uplink grant message, the UE may generate a feedback report to the eNodeB based on the instructions. The eNodeB may receive the feedback information in block 630. For example, the eNodeB may receive information regarding beam information and CSI. Baseband circuitry of the eNodeB may process the received feedback information to determine BRS-RP, CSI, CQI, RI, BI or other information provided by the UE.

In block 640, the eNodeB may update the coding and modulation schemes at the base station based on the CSI and beam information. For example, if the UE reports an increasing strength of the BRS-RP, the eNodeB may increase the speed of transmission to the UE. On the other hand, if the UE reports decreasing signal strength, the eNodeB may decrease the modulation and code rate used to transmit data to the UE. In addition to changing the modulation and code scheme used for transmission to the eNodeB, the eNodeB may update other parameters to improve performance of the eNodeB or the UE. For example, the eNodeB may determine that it is to use a different beam for transmissions to the UE.

In the description herein, numerous specific details are set forth, such as examples of specific types of processors and system configurations, specific hardware structures, specific architectural and micro architectural details, specific register configurations, specific instruction types, specific system components, specific measurements/heights, specific processor pipeline stages and operation etc. in order to provide a thorough understanding of the present disclosure. It will be apparent, however, that these specific details need not be employed to practice the present disclosure. In other instances, well known components or methods, such as specific and alternative processor architectures, specific logic circuits/code for described algorithms, specific firmware code, specific interconnect operation, specific logic configurations, specific manufacturing techniques and materials, specific compiler implementations, specific expression of algorithms in code, specific power down and gating techniques/logic and other specific operational details of computer system have not been described in detail in order to avoid unnecessarily obscuring the present disclosure.

Instructions used to program logic to perform embodiments of the disclosure can be stored within a memory in the system, such as DRAM, cache, flash memory, or other storage. Furthermore, the instructions can be distributed via a network or by way of other computer readable media. Thus a machine-readable medium may include any mechanism for storing or transmitting information in a form readable by a machine (e.g., a computer), but is not limited to, floppy diskettes, optical disks, Compact Disc, Read-Only Memory (CD-ROMs), and magneto-optical disks, Read-Only Memory (ROMs), Random Access Memory (RAM), Erasable Programmable Read-Only Memory (EPROM), Electrically Erasable Programmable Read-Only Memory (EEPROM), magnetic or optical cards, flash memory, or a tangible, machine-readable storage used in the transmission of information over the Internet via electrical, optical, acoustical or other forms of propagated signals (e.g., carrier waves, infrared signals, digital signals, etc.). Accordingly, the computer-readable medium includes any type of tangible machine-readable medium suitable for storing or transmitting electronic instructions or information in a form readable by a machine (e.g., a computer).

A module as used herein refers to any combination of hardware, software, and/or firmware. As an example, a module includes hardware, such as a micro-controller, associated with a non-transitory medium to store code adapted to be executed by the micro-contoller. Therefore, reference to a module, in one embodiment, refers to the hardware, which is specifically configured to recognize and/or execute the code to be held on a non-transitory medium. Furthermore, in another embodiment, use of a module refers to the non-transitory medium including the code, which is specifically adapted to be executed by the microcontroller to perform predetermined operations. And as can be inferred, in yet another embodiment, the term module (in this example) may refer to the combination of the microcontroller and the non-transitory medium. Often module boundaries that are illustrated as separate commonly vary and potentially overlap. For example, a first and a second module may share hardware, software, firmware, or a combination thereof, while potentially retaining some independent hardware, software, or firmware. In one embodiment, use of the term logic includes hardware, such as transistors, registers, or other hardware, such as programmable logic devices.

Use of the phrase ‘configured to,’ in one embodiment, refers to arranging, putting together, manufacturing, offering to sell, importing and/or designing an apparatus, hardware, logic, or element to perform a designated or determined task. In this example, an apparatus or element thereof that is not operating is still ‘configured to’ perform a designated task if it is designed, coupled, and/or interconnected to perform said designated task. As a purely illustrative example, a logic gate may provide a 0 or a 1 during operation. But a logic gate ‘configured to’ provide an enable signal to a clock does not include every potential logic gate that may provide a 1 or 0. Instead, the logic gate is one coupled in some manner that during operation the 1 or 0 output is to enable the clock. Note once again that use of the term ‘configured to’ does not require operation, but instead focuses on the latent state of an apparatus, hardware, and/or element, where in the latent state the apparatus, hardware, and/or element is designed to perform a particular task when the apparatus, hardware, and/or element is operating.

Furthermore, use of the phrases ‘to,’ ‘capable of/to,’ and or ‘operable to,’ in one embodiment, refers to some apparatus, logic, hardware, and/or element designed in such a way to enable use of the apparatus, logic, hardware, and/or element in a specified manner. Note as above that use of to, capable to, or operable to, in one embodiment, refers to the latent state of an apparatus, logic, hardware, and/or element, where the apparatus, logic, hardware, and/or element is not operating but is designed in such a manner to enable use of an apparatus in a specified manner.

The embodiments of methods, hardware, software, firmware or code set forth above may be implemented via instructions or code stored on a machine-accessible, machine readable, computer accessible, or computer readable medium which are executable by a processing element. A non-transitory machine-accessible/readable medium includes any mechanism that provides (i.e., stores and/or transmits) information in a form readable by a machine, such as a computer or electronic system. For example, a non-transitory machine-accessible medium includes random-access memory (RAM), such as static RAM (SRAM) or dynamic RAM (DRAM); ROM; magnetic or optical storage medium; flash memory devices; electrical storage devices; optical storage devices; acoustical storage devices; other form of storage devices for holding information received from transitory (propagated) signals (e.g., carrier waves, infrared signals, digital signals); etc., which are to be distinguished from the non-transitory mediums that may receive information there from.

Instructions used to program logic to perform embodiments of the disclosure may be stored within a memory in the system, such as DRAM, cache, flash memory, or other storage. Furthermore, the instructions can be distributed via a network or by way of other computer readable media. Thus a machine-readable medium may include any mechanism for storing or transmitting information in a form readable by a machine (e.g., a computer), but is not limited to, floppy diskettes, optical disks, Compact Disc, Read-Only Memory (CD-ROMs), and magneto-optical disks. Read-Only Memory (ROMs), Random Access Memory (RAM), Erasable Programmable Read-Only Memory (EPROM), Electrically Erasable Programmable Rcad-Only Memory (EEPROM), magnetic or optical cards, flash memory, or a tangible, machine-readable storage used in the transmission of information over the Internet via electrical, optical, acoustical or other forms of propagated signals (e.g., carrier waves, infrared signals, digital signals, etc.). Accordingly, the computer-readable medium includes any type of tangible machine-readable medium suitable for storing or transmitting electronic instructions or information in a form readable by a machine (e.g., a computer)

Reference throughout this specification to “one embodiment” or “an embodiment” means that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment of the present disclosure. Thus, the appearances of the phrases “in one embodiment” or “in an embodiment” on “in some embodiments” in various places throughout this specification are not necessarily all referring to the same embodiment. Furthermore, the particular features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

In the foregoing specification, a detailed description has been given with reference to specific exemplary embodiments. It will, however, be evident that various modifications and changes may be made thereto without departing from the broader spirit and scope of the disclosure as set forth in the appended claims. The specification and drawings are, accordingly, to be regarded in an illustrative sense rather than a restrictive sense. Furthermore, the foregoing use of embodiment and other exemplarily language does not necessarily refer to the same embodiment or the same example, but may refer to different and distinct embodiments, as well as potentially the same embodiment.

Some portions of the detailed description are presented in terms of algorithms and symbolic representations of operations on data bits within a computer memory. These algorithmic descriptions and representations are the means used by those skilled in the data processing arts to most effectively convey the substance of their work to others skilled in the art. An algorithm is here and generally, conceived to be a self-consistent sequence of operations leading to a desired result. The operations are those requiring physical manipulations of physical quantities. Usually, though not necessarily, these quantities take the form of electrical or magnetic signals capable of being stored, transferred, combined, compared and otherwise manipulated. It has proven convenient at times, principally for reasons of common usage, to refer to these signals as bits, values, elements, symbols, characters, terms, numbers or the like. The blocks described herein can be hardware, software, firmware or a combination thereof.

It should be borne in mind, however, that all of these and similar terms are to be associated with the appropriate physical quantities and are merely convenient labels applied to these quantities. Unless specifically stated otherwise as apparent from the above discussion, it is appreciated that throughout the description, discussions utilizing terms such as “defining,” “receiving.” “determining.” “issuing,” “linking,” “associating.” “obtaining,” “authenticating,” “prohibiting,” “executing,” “requesting,” “communicating,” or the like, refer to the actions and processes of a computing system, or similar electronic computing device, that manipulates and transforms data represented as physical (e.g., electronic) quantities within the computing system's registers and memories into other data similarly represented as physical quantities within the computing system memories or registers or other such information storage, transmission or display devices.

The words “example” or “exemplary” are used herein to mean serving as an example, instance or illustration. Any aspect or design described herein as “example’ or “exemplary” is not necessarily to be construed as preferred or advantageous over other aspects or designs. Rather, use of the words “example” or “exemplary” is intended to present concepts in a concrete fashion. As used in this application, the term “or” is intended to mean an inclusive “or” rather than an exclusive “or.” That is, unless specified otherwise, or clear from context, “X includes A or B” is intended to mean any of the natural inclusive permutations. That is, if X includes A; X includes B; or X includes both A and B, then “X includes A or B” is satisfied under any of the foregoing instances. In addition, the articles “a” and “an” as used in this application and the appended claims should generally be construed to mean “one or more” unless specified otherwise or clear from context to be directed to a singular form. Moreover, use of the term “an embodiment” or “one embodiment” or “an implementation” or “one implementation” throughout is not intended to mean the same embodiment or implementation unless described as such. Also, the terms “first.” “second.” “third.” “fourth,” etc. as used herein are meant as labels to distinguish among different elements and may not necessarily have an ordinal meaning according to their numerical designation.
